Integrated Spa heating times

[VCL123]

I recently had a pool / integrated Spa installed. I am running a jandy vsp set at 2750 for spa and 2250 for spa heat. I have been trying to get my spa heated faster and to a higher temp.

With the ambient air temp of 70 and starting water temp of 62. I was able to get to a maximum of 84 with a solar cover. This was after 5 hours of heating. I am unable to get past that temp. (I'm guessing because the ambient air temp dropped to 60). I was able to hold steady at 84, even after several hours of use.

Is this normal?

Welcome to the forum!
Can you fill out your signature with what equipment you have?
No, that is not normal. Tell us more about your pool/spa system.
I suggest you read ABC's of Pool Water Chemistry.

Thanks for the reply. I have all Jandy equipment.

Jandy has already come out because the heater kept giving off a "check louvers" error. It works now but takes a really long time to heat.

The pool is 36x16. 5 feet on the right is a 1 foot in depth shelf. The spa is integrated 8x8 with 4 feet inside and 4 outside.


VSP for filtration, 2HP for spa jets, another 2HP for water features. JXI Heater, Nature2 Chlorinator.

What model JXI heater do you have?

How many BTUs?

It is 400k natural gas. I wonder if it's the regulator. I would imagine the regulator works much like a gas grill regulator. If it isn't primed correctly the system goes into safety mode.

Has the gas pressure been checked both before the heater turns on and with it operating?

Jandy came out a few weeks back because the heater wouldn't fire at all. But I don't believe the pressure was ever tested.

Have a qualified gas technician come out and check your gas pressures and gas feed to the heater.

Will do. Thank You. I will ask my builder to have Jandy come out again. The problem is getting in touch with the him.
